Abstract
The invention discloses conductive ink for printing. The conductive ink is prepared from the following substances in parts by weight: 20-30 parts of bisphenol A glycidyl ether epoxy resin, 4-5 parts of epoxy curing agent, 1-3 parts of nanometer silver powder, 4-6 parts of nanometer copper powder, 5-10 parts of malonic acid, 40-50 parts of tetrahydrofuran and 3-7 parts of polyethylene glycol. The conductive ink for printing disclosed by the invention is friendly to the environment, and good in conductivity, and especially has good binding force on difficult-to-print glass, metal and plastic films. According to the conductive ink, the epoxy curing agent is optimized. The conductive ink has the advantages that the conductive ink can be cured with epoxy resin at normal temperature, and is fire-retardant and non-toxic, and the cured product is high in strength and stability. Compared with the prior art, the conductive ink has significant progress. The electrical conductivity of the ink is improved by adopting the nanometer copper powder and the nanometer silver powder.
Description
Technical field
The invention belongs to technical field of ink, be specifically related to a kind of printing electrically conductive ink.
Background technology
Traditional etch printing method need adopt ammonia alkali class etching solution corrosion sheet material, and etching solution contaminative is larger, and the water expending during rinsing sheet material is more.The whole world is more and more higher for the cry of " low-carbon (LC) " now, promotes the use of printing conductive inks and replaces engraving method, and it is imperative that " green " prints conducting wire.Avoid the use of volatile organic solvent, development environment close friend's printing will inevitably attract increasing sight with electrically conductive ink.And possess the electrically conductive ink of different specific conductivity fillers, and in conduction high polymer, add conductive filler material, prior development direction that the research that promotes ink conductivity becomes printing-ink.
Summary of the invention
Technical problem to be solved by this invention is: provide that a kind of strong adhesion, resistance are little, the printing conductive inks of good stability.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of printing conductive inks, is comprised of the material of following mass fraction: 20～30 parts of dihydroxyphenyl propane glycidyl ether based epoxy resins, 4～5 parts of epoxy hardeners, 1～3 part of nano-silver powder, 4～6 parts of copper nanoparticles, 5～10 parts of propanedioic acid, 40～50 parts of tetrahydrofuran (THF)s, 3～7 parts of polyoxyethylene glycol.
Described copper nanoparticle particle diameter is 3～8nm.
Described nano-silver powder particle diameter is 2～5nm.
Described epoxy hardener is the T31 type epoxy hardener that Jinan Yi Sheng company limited produces.
The number-average molecular weight of described polyoxyethylene glycol is 300～500.
Beneficial effect of the present invention: printing conductive inks environmental friendliness of the present invention, good conductivity, especially has good bonding force to glass, metal, plastics film difficult and brush.The present invention is preferred epoxy hardener, its advantage is can be at normal temperatures and epoxy resin cure, difficult combustion, nontoxic, and its cured article intensity and stability are high, have significant progress with existing public technology.The present invention has adopted copper nanoparticle and nano-silver powder, has improved the conductivity of ink.
